Volume-density ratio and elastic properties of Armenian volcanic highland effusives and xenoliths in high thermobaric conditions

(in Croatian)

Abstract

Complex experimental research of elastic properties and density of volcanics, effusives and their xenoliths in Armenian volcanic highland provided main characteristics of vertical changes in physical properties of volcanic rock in tectonic mobile structures. The experiments point to a decrease of thermoelastic stress values in lower layers of the Earth’s crust.
